[0020] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0021] In order to solve the problem that the shoulder cushion gum laminating device in the prior art is prone to detach from the belt layer drum when laminating the shoulder cushion gum, the present invention provides a shoulder cushion gum laminating device.

[0022] Please refer to Figure 1 and Figure 2 , a shoulder cushion gum laminating device includes a belt layer drum assembly 20 and a first pressure roller assembly 40. An adsorption mechanism is provided on the belt layer drum assembly 20 to adsorb the gum on the belt layer drum assembly 20 when the gum approaches the belt layer drum assembly 20; the first pressure roller assembly 40 is movably arranged relative to the belt layer drum assembly 20 to abut against the belt layer drum assembly 20 and press the gum onto the belt layer drum assembly 20 when approaching the belt layer drum assembly 20.

[0023] The shoulder cushion gum laminating device of the present invention is provided with an adsorption mechanism on the belt layer drum assembly 20. When one end of the cushion gum approaches the belt layer drum assembly 20, the adsorption mechanism can adsorb the gum onto the belt layer drum assembly 20, so that the cushion gum is sequentially laminated along the surface of the belt layer drum. Further, in order to prevent the cushion gum from being thrown out during the rotation of the belt layer drum, the present invention also provides a first pressure roller assembly 40. The first pressure roller assembly 40 is used to push the gum to fit with the belt layer drum and prevent it from being thrown out. Through the above adsorption mechanism and the first pressure roller assembly 40, the problem that the cushion gum does not detach from the belt layer drum during lamination is ensured, and the generation of air pockets and bubbles is avoided.

[0024] A joint part is provided on the belt layer drum assembly 20. The adsorption mechanism includes: a magnetic clamping rod mechanism 41 and a magnetic member. The magnetic clamping rod mechanism 41 is movably arranged relative to the belt layer drum assembly 20; the magnetic member is arranged around the belt layer drum assembly 20 or inside the belt layer drum assembly 20 to attract the magnetic clamping rod mechanism 41 to approach the belt layer drum assembly 20 through magnetic attraction and press the gum onto the belt layer drum assembly 20.

[0025] In this embodiment, the joint part is the position on the belt drum assembly for fitting with the end of the rubber compound. The adsorption mechanism is designed based on the principle of magnetic attraction. Specifically, a pair of magnetic parts are arranged on the joint part of the belt drum. The magnetic parts can be made of magnetic metal materials, such as magnets. The two magnetic parts are respectively located on both sides of the joint part on the belt drum. When the belt drum assembly 20 rotates, the magnetic parts attract the magnetic clamp rod mechanism 41 to the belt drum through magnetic attraction, so that the cushion rubber is always clamped between the magnetic clamp rod mechanism 41 and the magnetic parts.

[0026] In addition, the adsorption mechanism can also adopt the way of electromagnetic attraction, so that the magnetic clamp rod mechanism 41 and the belt drum assembly 20 can automatically clamp the cushion rubber under the action of magnetic attraction.

[0027] The second pressure roller assembly in this embodiment is arranged on the conveyor belt assembly 10 and includes a plurality of rollers, which can approach or move away from the belt drum simultaneously. The second pressure roller assembly is mainly used for rolling the joint of the end of the cushion rubber to prevent the problem of loose adhesion at the joint. The plurality of pressure rollers are arranged along the direction perpendicular to the conveying direction of the cushion rubber, and the plurality of pressure rollers are arranged in one-to-one correspondence with the plurality of cushion rubbers to roll each cushion rubber respectively.

[0028] The second pressure roller assembly is arranged at the end of the conveyor belt assembly. When the belt drum assembly winds the rubber compound, since the rubber compound has been cut on the conveyor belt assembly, during the process of the belt drum winding the rubber compound, especially when it is almost finished winding, only a small part of the rubber compound is still on the conveyor belt assembly. At this time, the rubber compound is prone to shift left and right, resulting in problems such as deviation during the winding of the belt drum. However, the second pressure roller assembly in this embodiment can make the rubber compound closely adhere to the conveyor belt assembly to prevent the rubber compound from shifting.

[0029] The shoulder cushion rubber fitting device further includes a distance adjustment component 50, which is arranged on the conveyor belt assembly 10 to adjust the distance between two rubber compounds.

[0030] The distance adjustment component 50 can adjust the distance between each cushion rubber to ensure that multiple cushion rubbers can be wound on the belt drum according to the preset positions.

[0031] The shoulder cushion rubber fitting device further includes a cutting component 60, which is arranged on the conveyor belt assembly 10 to cut the rubber compound.

[0032] The shoulder cushion rubber fitting device further includes: a conveyor belt driving mechanism, which is drivingly connected to the conveyor belt assembly 10 to drive the conveyor belt assembly 10 to move; a control switch, which is arranged on the conveyor belt assembly 10 and is control-connected to the conveyor belt driving mechanism to control the start and stop of the conveyor belt driving mechanism by an interval of a preset time and control the length of the rubber compound cut by the cutting component 60.

[0033] Its cutting principle is as follows: The conveying speed of the conveyor belt assembly 10 is constant. The control switch controls the start and stop of the driving mechanism according to the preset time, so that the conveyor belt assembly 10 always conveys the tread according to the predetermined time. Then, whenever the conveyor belt assembly 10 stops, the cutting assembly 60 cuts the tread, and the length of each tread is controlled by controlling the moving time and speed of the conveyor belt assembly 10.

[0034] The shoulder pad rubber laminating device further includes a driving assembly, and the driving assembly is connected to the magnetic clamping rod mechanism 41 to drive the magnetic clamping rod mechanism 41 to approach or move away from the belt layer drum assembly 20.

[0035] The driving assembly can adopt a driving cylinder. The driving cylinder drives the magnetic clamping rod mechanism 41 to approach the belt layer drum. Then, the magnetic parts on the belt layer drum adsorb the magnetic clamping rod mechanism 41 on the belt layer drum, so as to press the pad rubber on the belt layer drum.

[0036] The adsorption mechanism includes: a plurality of suction cups, and the plurality of suction cups are arranged at intervals along the circumferential direction of the belt layer drum assembly to adsorb the rubber compound on the belt layer drum assembly, preventing the rubber compound from falling off or being not closely attached to the belt layer drum when winding around the belt layer drum. The shoulder pad rubber laminating device further includes a vacuum system, and the vacuum system is connected to the adsorption mechanism to generate suction force for the suction cups by evacuating.

[0037] The present invention also provides a molding machine, and in this molding machine, the shoulder pad rubber is laminated by the above-mentioned shoulder pad rubber laminating device.

[0038] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0039] A tire molding method of the present invention focuses on the design of the pad rubber feeding system of the molding machine, improves the shoulder pad rubber laminating device. The semi-finished pad rubber is unrolled by the unrolling assembly 70, automatically centered by the distance adjusting assembly 50, conveyed to the automatic constant-length ultrasonic cutting assembly 60 for cutting. After the pad rubber reaches the predetermined length, it reaches the pad rubber front template at one end of the conveyor belt assembly 10 close to the belt layer drum. After the front template is automatically corrected, it reaches the belt layer drum. After being vacuum adsorbed on the belt layer drum plate and clamped by the magnetic clamping rod, multiple pressing rollers perform pressing, and finally the joint is pressed to complete automatic lamination.

[0040] During specific use, the main process steps are as follows:

[0041] The pad rubber is unrolled from the spool material roll by the pad rubber unrolling assembly 70. After being automatically centered by the pad rubber automatic distance adjusting assembly 50, the distance between the left and right pieces of pad rubber is adjusted to the width required by the tire formula.

[0042] After the cushion rubber is automatically sized by the automatic cushion rubber sizing switch and then cut by the ultrasonic cutting assembly 60, the cushion rubber is transported to the front end of the cushion rubber front conveying template;

[0043] The cushion rubber is rectified by the automatic rectifying assembly. After the cushion rubber is adjusted, it is transported to the proximal end of the belt drum plate.

[0044] The cushion rubber moves to the adsorption drum plate of the belt layer drum. The front end of the cushion rubber is adsorbed at the adsorption vacuum suction cup, and at the same time, the magnetic clamping rod is magnetically adsorbed to the belt drum plate to prevent the end from falling during the rotation and fitting process of the belt drum.

[0045] While the belt drum rotates, multiple pressing rollers press the cushion rubber. After the belt drum rotates nearly one week, the magnetic clamping rod mechanism 41 retracts the clamping rod into the device. At this time, multiple pressing rollers press the rear end joint and the front end joint of the cushion rubber to complete the fitting of the cushion rubber;

[0046] The shoulder cushion rubber fitting device of the present invention enriches the method of tire production and provides a new method for cushion rubber fitting. In the past, after the cushion rubber was fitted on the forming drum, during forming, it was necessary to go through the expansion of the forming drum. During the expansion of the intermediate capsule of the forming drum, the cushion rubber would be stretched in the circumferential direction. The stretching of the cushion rubber on the entire circumference was not uniform stretching, which would have a certain impact on the quality of the tire. When the cushion rubber is fitted on the belt layer drum and formed on the forming drum, the cushion rubber will not be stretched, and it can maintain the uniform distribution of the cushion rubber in the circumference, improving the quality of the tire. And the cushion rubber fitting can be automatically completed throughout the process, thereby improving production efficiency and reducing the labor intensity of workers.

[0047] After the cushion rubber is fitted on the belt layer drum, it is avoided being stretched during forming on the forming drum, which can ensure the uniform distribution of the cushion rubber in the circumference of the tire embryo, greatly improving the dynamic balance index of the tire and enhancing the quality of the tire.

[0048] The cushion rubber fitting can be automatically completed throughout the process, thereby improving production efficiency and reducing the labor intensity of workers.
